I use this device only for my mood ukulele as they more often annoyed by my rough sport or simply by longer life. The vote will take with this device than 5 minutes and it is enough if one lies down on a table edge in front of him. So you must not stop right at the Ukulele.
Previously I agree my Ukulele always with my keyboard and my hearing but clearly that took more time and since I do not play my clunky keyboard, I had it standing here just for this reason ...
